BMW 7 series audio install

Well this is very exciting for me. Thursday I received a message asking if I would like to do an install on a 2001 BMW 740. After talking to him for two days I took a ride up to him on Saturday to meet him and the car. After him reading about me and my work he had no problem handing the keys over to take it home. He left Monday for a 2 week vacation.

Enough with that story, time to talk about the install.

Goodies include

Q 450.4 - Image Dynamics 4-Channel 450 Watt Amplifier

Q 1200.1 - Image Dynamics 1-Channel 1200 Watt Amplifier

IDQ12V2.D2 - Image Dynamics 12" IDQ $149.99 x 2

130CVX - Focal 5.25 " Polyglass Coaxial Speakers

MTX re-Q Signal Processor

JL CleanSweep CL441DSP

Stinger Pro 3 Series 6 Channel

Head rest tv's

Kicker 12 Guage S series 150ft

Kicker PKD1

FOCAL 165VR3 3 WAY COMPONENT SET

Dynamat 10455 Xtreme Bulk Pack 9 Sheets

This install will very much help my skills and expand them to fiberglass and custom boxes.

Re: BMW 7 series audio install

sounds like a fun build.
take tons of pics. one question though.. how are you going to incorporate the jl cleansweep and the mtx req? PLEASE let me know how your mtx req install goes. i did an install on my lexus with a req and wow. ive had quite a few problems, i managed to fix all of them, except the engine noise that i get from it!!!!!!!!!! let me know how your install with the req goes.

As of right now I am talking to a few people on the BMW forum. Some tell me that I can just use the preouts of the head unit and wire them up to female rca ends and run them to the new amps. Others are saying that the JL is needed. I will let you know.

I will make sure to take plenty of pictures.

any updates on this build?
anyways, thanks, yeah let me know.
and i think you'll definitely need teh req or the cleansweep if your going to stick with stock hu. i would definitely do it. those femal rcas wont give you as good clean sound as the processor will. i thought about it also before i got my req. jl makes some of those female ends that connect to the speaker leds and conver it into rca outputs, but they'll give you much lower quality sound (or from the research that i did, thtas what i found out).

Re: BMW 7 series audio install

Today i worked on the kick panels. The reason for this is there is no stock location for a 6.5 inch speaker in the door. Also this will help imaging a bit by having them facing the drive and passenger.

Drilled holes to help the fiberglass hold to the stock panel.

Laying down the foil and tape to protect the carpet.

Laying the cloth and resin

While that was curing I took off the door panel to take a look at the mid and tweeters.

The owner said that the speakers were upgraded but he did not know what they were. All that was upgraded was the tweeter.

Have to make a bracket to hold the smaller mid but will be well worth it.
